    1 {
        Write-Host "Day 1: Sunday"
    }
    2 {
        Write-Host "Day 2: Monday"
    }
    3 {
        Write-Host "Day 3: Tuesday"
    }
    4 {
        Write-Host "Day 4: Wednesday"
    }
    5 {
        Write-Host "Day 5: Thursday"
    }
    6 {
        Write-Host "Day 6: Friday"
    }
    7 {
        Write-Host "Day 7: Saturday"
    }
    default {
        Write-Host "Invalid number. Please enter a number from 1 to 7."
    }
}

Enter a number from 1 to 7: 3

Day 3: Tuesday

Example 2:

# Menu Options
Write-Host "AI Operations Menu:"
Write-Host "1. Stable Diffusion"
Write-Host "2. AI Analysis"
Write-Host "3. Exit"

$choice = Read-Host "Enter Menu Option 1 - 3"

$choice = [int]$choice

switch ($choice) {
    1 {
        Write-Host "You selected: Stable Diffusion"
    }
    2 {
        Write-Host "You selected: AI Analysis"
    }
    3 {
        Write-Host "Exiting.."
    }
    default {
        Write-Host "Invalid choice. Please enter a valid option (1, 2, or 3)."
    }
}

Enter Menu Option 1 - 3: 2
